Consider the polynomials f(t) = t + 1 and g(t) = (t + 2)(t + k), where k is an arbitrary constant. For which values of the constant k are the three polynomials f(t), tf(t) and g(t) a basis of P2?

This will happen when the matrix of coefficients

is nonsingular. Evaluate its determinant, and find the values of for which it is nonzero.
